AI Insight: UCTT Financial Trends

A $162M net loss in Q2 2025 gutted equity by ~$160M and the damage lingers — UCTT has not returned to profitability through Q1 2026.

• Revenue slipped from $563M in Q4 2024 to $507M in Q4 2025, a modest but consistent four-quarter decline.

• Operating income collapsed from $26M in Q4 2024 to $11M by Q3 2025, then held flat through Q1 2026.

• Equity eroded from $874M in Q4 2024 to $628M in Q1 2026, a $246M decline over five quarters.

• Operating cash flow turned negative at -$33M in Q1 2026, reversing a brief period of positive FCF generation.

⚠ Total debt rose to $602M in Q1 2026 from $481M in Q4 2024 while equity shrank — leverage is visibly increasing.

⚠ Operating income has stalled at $11M for three consecutive quarters; any further revenue softness could push it negative again.

⚠ Q1 2026 operating cash flow of -$33M warrants monitoring — a sustained negative trend would pressure the balance sheet further.

AI Insight: UCTT Ratio Trends

A large Q2 2025 impairment dragged TTM profitability deeply negative, masking an underlying operating margin that has stabilized near 2% across the last three quarters.

• Operating margin collapsed to -27.3% in Q2 2025 before recovering to 2.1% in Q3 2025 through Q1 2026, suggesting a one-time charge drove the trough.

• ROIC has deteriorated from 10.8% in Q2 2024 to 3.7% in Q1 2026, reflecting sustained erosion in capital productivity.

• Net profit margin remains negative in Q1 2026 at -3.4%, and the company has not posted positive NPM in three of the last four reported quarters.

• D/E rose from 0.57 in Q4 2024 to 0.96 in Q1 2026, indicating modestly increasing leverage over the past year.

⚠ The Q2 2025 spike to -90.1% ROE and -78.8% ROIC suggests a large write-down; confirm whether charges are fully behind the company.

⚠ Operating margin has plateaued at 2.1% for three straight quarters — watch for improvement toward the 4%+ levels seen in Q2–Q4 2024.

⚠ D/E climbing to 0.96 alongside persistently negative net income warrants close monitoring of debt serviceability and covenant headroom.
